Abstract: An electrodeless lamp which operates with a high efficiency and with a lower cooling requirement. The bulb is rotated at a high speed which results in a substantial increase in efficiency. Because more of the input energy is converted to light, and less to heat, the pressure of the cooling fluid source may be reduced, resulting in a less noisy system.

Abstract: A metal vapor/inert gas laser comprises a laser tube containing an inert gas and a metallic material capable of vaporizing and lasing, a microwave energy source, and a slow wave structure proximate the laser tube for coupling microwave energy from the source to the metal vapor in the laser tube. A non-metallic electronegative species can be substituted for the metallic material in the laser tube.

Abstract: A microwave powered discharge device which utilizes a TM.sub.NMO cavity. A conductive body is positioned at a null in a discharge device which utilizes a TM.sub.210 cavity to reduce direct coupling from the microwave coupling means, e.g., slot of the cavity. A plurality of TM.sub.110 cavities are ganged together, and a single discharge tube extends through all of the cavities.

Abstract: The present invention relates to discovery that oxygen may be used to stabilize the efficiency and performance of an excimer laser. Therefore, oxygen is not a contaminant to be minimized but rather a necessary part of an excimer lasing composition.

Abstract: The invention provides circuit matching elements primarily for integrated circuits and particularly for monolithic microwave integrated circuits.A transmission line in accordance with the invention is provided with a thin metallic film deposition disposed in the signal propagation path. The effect of the film is to increase the specific capacitance of the line without decreasing the specific inductance. The result is a slowing down and therefore a decrease of the wavelength of signals in the line.An example of an implementation of the invention is a coplanar waveguide having a central thick conducting line element (32) and outer thick conducting line elements (28,30) mounted on a substrate (21). The central element overlies a thin metallic film (22) which also underlies the outer conducting line elements and is insulated from the latter by polyamide insulation (24,26).
